When, I am walking around with either a guitar plugged in or a lavaliere microphone. I continue to get pops and static surging sounds. Is there a way to fix this
Hello Although it has 2 antennae the AT201 is a single channel transmitter and receiver. As you move the transmitter about in relation to the receiver you are finding 'dead spots' in the room where the signal is reduced or even drops out completely. You can reduce the impact of this somewhat by doing the following things.
Make sure there is a clear line of sight between transmitter and receiver.
Move transmitter and receiver closer together
Do not locate the receiver near large pieces of metal or near other electrical equipment, particularly things that have strong magnetic fields like transformers (including amplifier power-supplies) CD or DVD players, hearing loop amplifiers and loop cables.
Turn off mobile phones and any other radio operated equipment that is not needed
Turn the trim control on the transmitter to the maximum output that you can without causing distortion. The stronger the original signal from the transmitter the lower the related noise will appear to be (called signal - noise ratio)
Turn the squelch control on the receiver up a bit to suppress noise - however doing so will reduce the strength of the output signal a bit so don't over do it.
Use good quality screened cable between the receiver and your amplifier. Unfortunately the AT201 only has an un-balanced mono jack socket so this cable will be more prone to pick up radio interference than a twin core plus screen (balanced) cable.
Make sure that your signal cable does not run parallel to, and close to, any mains electricity cables. If the signal cable needs to cross any mains cables it should do so at 90 degrees and the cables router well away from each other.
However the only real solution to this sort of problem is to use a full duplex (2 channel) transmitter / receiver system which will automatically switch to whichever channel is carrying the stronger signal. Typically these cost about 70% more than single channel units but they often use balanced cable outputs (stereo jack or xlr) which further reduce the propensity for noise due to interference.
